The first one should be Leather or Colt Coral if i am not wrong... Cant see clearly...
Mostly non-photosynthetic... One of the hardiest soft coral... Place them in Moderate flow and feeding of phytoplankton, coral food and trace elements is requires...
THe second if not wrong should be Star Polyps... They are closed now... Cant remember photosynthetic anot... But i have mine under lighting and growing well.. Dun let algae grow over them if not they will die... Require high flow, but dun place too near to the powerhead, the tissue will fly away...
The last one is Cauliflower coral, not a easy coral but if the condition is right... They thrive very well... Require high flow and a lot of phyto and coral food... Btw they are normally found hanging upside down in the wild... Place upright also can...
Give them some time to settle down... Normally corals will take some time to regain their full health...
